Retainer invoicing guide

Bill monthly retainers automatically and manage scope for ongoing clients.

Retainers provide predictable income — but only if you invoice consistently. Manual monthly billing leads to missed invoices and awkward "oops, forgot to bill you" conversations.

InvoyFlow recurring invoices generate and optionally send retainers on schedule — weekly, monthly, or custom.

Step by step

Define scope in writing

What is included in the retainer hours or deliverables.

Set the billing cycle

Monthly on the 1st is common — align with client budget cycles.

Create a recurring invoice

Fixed amount, auto-generated on schedule.

Track overage

Bill extra work as separate line items or invoices.

Review quarterly

Adjust retainer amount as scope grows.

Retainer vs deposit?

Retainers are ongoing monthly fees for reserved availability. Deposits are one-time upfront payments for a specific project.

Do unused hours roll over?

Define your policy in the contract — use-it-or-lose-it is common for consulting retainers.
